Okay, we know that Marvel already released an Ant Man movie and there is an Avengers Cartoon that has Wasp in it, however I believe Wasp should get some shine. Here character has went through alot.

Her relationship with Ant Man was not the best especially when he turned into Yellow Jacket. His attitude was completely off the wall. Now let's get into Wasp.

Janet van Dyne AKA Wasp was a daughter of a wealthy scientist named Vernon van Dyne. During an experiment, however, an alien monster was unleashed and Dr. van Dyne was killed. Her father's associate, Dr. Henry "Hank" Pym, had created a substance called "Pym particles", which allowed the user to grow or shrink in size, and had become the superhero Ant-Man; when Janet's father died, she convinced Pym to help her, and he gave her a supply of "Pym particles" and subjected her to a procedure which granted her the ability to, upon shrinking, grow wings and fire blasts of energy, which she called her "wasp's stings". As Ant-Man and The Wasp, they defeated the monster and sent it to its own dimension, and had several more adventures together.

The Wasp was in the Avengers with Ant Man, however she was an extremely large flirt especially with Thor, so she could get attention from Ant Man.
Ant Man had always loved Janet, but various things kept him from proposing to her from he wealth that she had from her family to all the flirting behavior that she did with Thor and other Male members of the Avengers.
One day, while he had still not fully mentally recovered from the stress of accidentally creating one of the Avengers' greatest enemy Ultron, Ant man had a lab accident with experimental gases. These caused a reaction in him that broke his inhibitions down, and induced a severe case of schizophrenia.
This further led to his break down and he told the Avengers that Ant Man is dead and only Yellow Jacket is around. The thing is he faked his own death to archive this and the only person to figure it out quick was Wasp.
Wasp decided to take advantage of his weaken mental state and got him to marry her. Then things really start going down from then on.

The story of Wasp and Ant Man is quite tragic and full of ups and downs. Both parties need to take blame in their relationship and also a lot of there relationship battles begun to spill into the Avengers team, even causing some serious disturbing destruction with the dynamics of the team.
Wasp is Unsung in my open because her full story with Hank will most likely never be told the right way and it's down right full of sadness and pain, oh and of course a couple of successful Avenger missions in between.
